Regular physical activity is widely recognized for its numerous health benefits, and one of the most significant advantages is the improvement of cognitive skills. Engaging in regular exercise boosts blood flow to the brain, promotes the release of neurotrophic factors that support brain health, and can enhance memory, learning, and overall cognitive function. Physical activity has also been linked to decreased risks of cognitive decline and various neurological disorders.

In contrast, the other options do not reflect positive outcomes associated with physical activity. Watching more television is typically linked to a sedentary lifestyle, which can lead to negative health consequences. Higher cholesterol levels are generally associated with poor dietary and lifestyle choices, while weight gain can occur due to inactivity and poor dietary habits. Regular physical activity usually contributes to weight management and a healthier body composition. Thus, the correct answer highlights one of the most beneficial aspects of maintaining an active lifestyle.
